What to expect on during your trip: - National Park Service
Indiana DunesEducationNational Park ServiceU.S. Department of the InteriorIndiana Dunes National LakeshoreEducation DepartmentReflections On Snow Summary: Discover why Indiana Dunes has one of the largest diversity of plant species in the National Park System. Explore many habitats, such as open dunes, forested dunes,wetlands or oak savannas that support rare species and this abundance of life. Objectives: students will be able to Name ways to protect and respect park resources, including animals in winter.Draw and explain a “story in the snow” using tracks and animal signsIdentify adaptations that enable animals to survive the winter.Identify animal homes and animal tracks.5. Name forest animals that are hibernating and that are active in the winter. What to expect on during your trip:Students will be presented with indoor winter ecology activities and an outdoor winter ski or hike if there isn’t enough snow. Often the groups split in two with half outside while the other half is inside. Rangers will also work with teachers to adapt the indoor/outdoor portions to specific requests. Setting: Paul H. Douglas Center for Environmental Education and Miller Woods. Trailis about one mile longGrade: 5th – 12th grade.Ratio of students to ranger: up to 15 is ideal. However, due to staffing limitations, we will try to accommodate larger groups within reason and with teacher’s assistance. Safety Issues: Trips /falls while hiking/skiing, cold weather. It is important to have students dress appropriately for the weather.Background Information: Winter is a harsh time for plants and animals. Through specialized adaptations and features, nature survives the bitter cold, lack of available water and food, and diminished light supply during this challenging time. The presence or lack of snow has profound effects on specific species of plants and animals as well. Since the beginning of time, the human species has had to deal with the weather and adapt to the conditions of the seasons. Perhaps winter has necessitated the need for the most creative functions. Examples of this can be seen by the use of snowshoes and skis. Prerequisite Classroom Activities: Prior to your visit to the Indiana Dunes National Lakeshore we suggest that you read over the following activities and incorporate them into your classroom teaching before or after your visit.1. Have students draw a collage of winter scenes.2. Cut out snowflakes and explain why each snowflake is unique.3. Have students describe their room at home. What would they need in this room to survive if they stayed there all winter?4. Ask the class to make up an imaginary animal. They should draw it and its tracks. They might want to write a story about where it lives and what it eats. 5. Winter Scavenger Hunt ActivityWinter Scavenger hunts give opportunity for children to look closer at nature. Have them look for signs of struggle, i.e. feathers, fur or blood on ground, predator/prey relationships, berries, ice formations, etc. Here are ideas you could put into your hunt:something that shows its winterSomething used for warmth in winterSomething that is asleep for winterSomething that tells us spring will comeSomething this is the beginning of a food chainSomething an animal uses for its homeSomething used by people today in winter6. Temperature Adaptations:When the ground is covered with snow, use a thermometer to compare the temperature above and below the snow. Discuss the insulating qualities of snow which will be demonstrated if the air temperature is well below freezing. Contrast air temperature between sun and shade.7. People Tracking:- Have two people, one relatively tall and the other short, walk side by side in snow. Have another person run alongside. - Have the group notice the differences in the tracks. - Now have two or more people make a “story in the snow: with the rest of the group not looking and then trying to figure out what happened. - Use the information they figured out when you go out and look for animal tracks.8. You’re one of a Kind: (sets the tone for exploration)- Form a circle and hand out pinecones to each person. - Tell them to examine it so carefully that they would be able to pick it out of a whole pile of pinecones. - During the next minute or two they look at it, feel it, smell it, then put all the cones in a bag. - Teacher dumps them out on the ground. - Each person must find his or her pinecones. - Afterwards ask them to explain what made their cone unique. - Sum up mentioning even though all cones seem alike they are “one of a kind”, Just like all other things in nature.Vocabulary: There were no words in the English language to adequately name the type of snowfall, so researchers use combinations of Northern Indian and Eskimo words. API (a-pee) the entire body of snow on the ground.PUKAK (pu-cock) -The bottom layer of API. The earth radiates heat that is trapped by all the snow. So the bottom snow melts and forms small caves and tunnels and prepares a habitat for lots of small creatures. Animals are protected from predators and seeds and water is available.If ice forms on top of snow, it restricts the air exchange - vegetation decaying in the PUKAK can cause too much hydrogen sulfide which in turn causes animals to get "drunk". They come out of their tunnels and run around in circles and often become dinner. Temperature is usually 33-34 degrees.SIQOQTAQ (sik-ak tuk) -Icy covering over the top of API formed by melting and refreezing or by rain on the snow. Means "the snow that makes the caribou's legs bleed". UPSIK (up-sick) -Snow that's been drifted over a wind-driven lake. It's hardpan snow and you cannot break through it. All the crystal edges have broken off. If you hit it with an anvil, the anvil would ring. Wolves and moose use it to travel on in winter because it's much easier to traverse than deep powder.QALI (ka-le) -Snow that collects on the trees above the ground. It eventually breaks the branches off the trees. (Some trees have evolved to have shorter branches.) Causes openings (forest windows) in the forest canopy, especially in the North Woods. The tree breaks off and next spring surrounding trees grow bigger branches. Those trees, of course, break off because there's more weight from the snow and the opening spreads. This can increase to 5 acres and then it usually stops because the wind blows the QALI off the trees. The whole process of succession then begins. QALI also bends over black spruce and cedar to form habitats for animals. Such as rabbit and deer.Adaptation any alteration in the structure or function of an organism or any of its parts that results from natural selection and by which the organism becomes better fitted to survive in its environment.Ecology the branch of biology dealing with the relations and interactions between organisms and their environment, including other anism a form of life composed of mutually interdependent parts that maintain various vital processes.Migration to pass periodically from one region or climate to another, as certain birds, fishes, and animalsFood Web a series of organisms interrelated in their feeding habits, the smallest being fed upon by a larger one, which in turn feeds a still larger one, etc.Indiana Content Standards: The Reflections on Snow program can assist teachers in meeting the following Indiana standards.Fourth GradeScienceLife ScienceSCI.4.3.2 2010 Observe, compare and record the physical characteristics of living plants or animals from widely different environments.
